Forms Engine Plugin

A hapi plugin for building GOV.UK form journeys with minimal code

Configuration-driven and extensible, built on Hapi.js. Handles routing, validation, state management, and GOV.UK Frontend rendering — so teams can focus on form design, not plumbing.

Configuration driven

Define form journeys through JSON — pages, fields, validation, and conditional logic — without writing custom route handlers or view logic.

Inclusive and accessible

Built on GOV.UK Frontend, ensuring forms meet WCAG standards and work with assistive technologies out of the box for all users of public services.

Open source and flexible

Extensible architecture with hooks for custom services, components, and page views. Integrates with any Hapi.js application.
